Heating circulators
Circulating Thermostats Open Circulator Systems Baths with Integral Circulators
Heating circulators with stainless steel bath tank for internal and external temperature applications. Units have powerful heating capacities for large closed or open external systems with simultaneous operation in the bath tank. Models are available with different bath sizes and operating facilities. Accessories: External PT100 sensors, bath fluids, tubing and adapters for connecting external systems. All models feature an integrated cooling coil for applications at or near ambient temperature.

  • Early warning system signals a lowering of bath fluid level
  • PID temperature control with drift compensation and electronically-adjustable pump capacity
  • RS232 interface

MA models: Features include Multi-Display (LED) for actual value, up to three set points, high/low temperature warning functions and high temperature protection. It is possible to calibrate three temperatures simultaneously.
ME models: Features include Multi-Display (LED) for actual value, up to three set points, high/low temperature warning functions and high temperature protection. It is possible to calibrate three temperatures simultaneously. Units have a bright VFD comfort display for simultaneous indication of internal/external set point and actual values, and PID cascade temperature control for highest internal and external temperature stability.
